South Korea: exports nearly double in October on AI chip boom

South Korea's exports nearly doubled in October 2026, driven by global demand for AI chips. According to data from the Ministry of Trade, Industry and Resources released on November 1 and reported by Reuters and Bloomberg, overseas sales reached $115.28 billion, up 93.7% from a year earlier — the second-highest monthly total on record and the strongest growth since January 1974.

What drove the jump

Semiconductors powered the result: chip exports jumped 259.4% to $56.44 billion, equivalent to 48.9% of everything the country sold abroad in the month. Computer exports, led by servers for AI services, surged 496.6%. The ministry attributes the performance to continued investment by large technology companies in AI facilities, which kept prices and volumes high.

The calendar caveat

The headline, however, comes with an important caveat: the calendar helped. The Chuseok holiday fell in October last year and in September this year, giving October 2026 more working days. Adjusted for working days, exports rose 76.1% — still an extraordinary pace, but below the 93.7% unadjusted comparison. September was actually larger in absolute value, at $121.1 billion in total exports.

By destination, sales to the United States grew 185.8% to $24.9 billion and to China 134% to $27 billion, led by AI-related goods. Imports rose 36% to $72.78 billion, producing a trade surplus of $42.5 billion. From January to October, exports reached $930 billion, and the ministry expects the $1 trillion mark to be crossed as early as November — which would make South Korea the fourth economy to reach that level, after the United States, China and Germany.

The backdrop helps explain the figure: Samsung and SK hynix, South Korea's two memory giants, are enjoying a cycle of record profits on demand for high-bandwidth memory (HBM) and DRAM for AI data centers. At the same time, the data arrives amid a correction in technology stocks, as investors question whether the huge spending on AI infrastructure will pay off at the same speed — on Friday, the Kospi index fell 3.5%, with SK hynix down 7% and Samsung down 3%.

What it means

The picture, therefore, is twofold: the trade balance confirms that the AI investment cycle is still running at full speed, but the ministry itself and the market note that part of October's jump is a calendar effect — and that the concentration in AI chips, almost half of exports, leaves the country more exposed to any turn in the memory cycle.
